This is HD 189733b, which is the latest planet to be spied by the Hubble Space Telescope. It is like many planets except for one fascinating feature: it’s blue.
The problem is that the Jupiter-sized planet is too close to its star to have liquid water. It orbits its star at a close range every 2.2 days just 63 light-years away in the constellation Vulpecula (the Fox).
Scientists believe the blue light is caused by clouds of liquid glass — a reflection by silicate clouds and absorption by sodium atoms. Probably not ideal for a picnic but it is still better than raining molten lead over on Corot 7b.
